how pissed should I be...?

Ladies I need advice.  I am FUMING! My fiancé and I came home from a nice dinner with a couple of friends. We were both in the mood and I lit candles, put on music and decided to get the party started.  I began giving him a bj. As normally happens I started having intense neck pain. He had his hand on my neck which started as gently rubbing my neck, but ultimately turned into him pressing down hard on my neck. I went to move his arm away right as he started to come.  All of the sudden he freaked out saying "that was the worst ever" He said " how could you move away right as I started to come I still have half a load in there."  I got immediately offended. He went on to say what he meant to express was "that's as the worst ending ever," like How could you come so far and not finish strong.  While I understand his sentiment I can't get over the way he expressed it. How dare he say that was the worst ever. Aren't guys thankful for bjs anymore or effort their partners put in?! What the hell ever happened to constructive criticism being delivered in a nice way?!  He is on the couch tonight for
Sure but I still feel so much hurt and anger. What should I do?
